To all whom it may concern:

Be it known that l, Pmnir A. Bowen, c citizen of the United States,residing at Lynn, county of Essex, State of Massechnsetts, have inventedan Improvement in Lasts, of which the following description, inconnection with the accompanying drewing, is a specification, likecharacters on the drawing representing like ports. This inventionrelates to divided lasts end has for its object to provide it lost ofthis type which can he used throughout all the successive operationsrequired in the menthus 0 vinting the hoseslast in the shoectter theletter is partially finished.

In the manufacture of shoes it is now the common rectioe to use one typeof lost for the lasting operation and to remove this last and substitutefor it e so-celled follower lest which is need during" some of thesubsequent or finishing operations of the shoe. This necessitates twolnsts for each shoe, end where the styles or shapes of lasts are changedit necessitates the mohing of two lests of every style and shape.

My improved lost is made with e fore nrt and e heel pert end with meansfor loo ring these two parts together so as to provide it lest ofsucient rigidit to he used in the lasting operetion, sei novelconstruction by which the heel port by to, shorten the lost when it isto he removed from or inserted into n shoe without stretching theletter. I

A. last embodying my invention is portionlorly useful in the manufactureof pumps and all types of low shoes because by moons of it the entireoperation of menufecturin the pump and low shoes can he completed on onelast end the lost can he-rernoved from the shoe without stretching theripper edge of the quarter.

The features wherein my invention resides will he more fullyhereineiiter described and then pointed out in the eppended cleiin.

In the drewings l have own c selected embodiment of my invention whichis idles tretiv of the principle thereof end which I will now proceed todescrihe- Figure 1 is a. side view of the lost needs Fig. 2

is a. view partly in section showing lest having e the last shortenedfor insertion into or removal from n shoe; Fig. 3 is a, rear view ofthefore port of the lost.

My improved lest is out diagonally across the instep portion along theline 1 thereby to constitute a, fore port 2 end a heel part 3. The heelport is shown as having e metal heel plate 4 thereon, and is providedwith n last-pin-receiving socket 5, ell as nsnel. The heel pert 3 isedepted to have a sliding movement on the fore pert 2- elong the line ofdivision 1, thereby to shorten the last, as shown in dotted lines Fig.2, end

said fore part has also the capability of e swinging movement rehzutiveto the fore part, as indicated in full lines Fig. 2.

'lo guide the two ports of the lost in their sliding nioveinent l haveherein shown the fore part of thelastas provided with e guiding groove 6in which is received a rib 7 stormed on the heel pert oiithe lost. Thisrib is herein shown es termed by melt ing it groove 8 in the heel portof the lost end then securing in sold groove loy glue or otherwise ncylinhlricnl guiding member Z of e size to fit the igroove v a The twoports of the lost ere rigidly held in their operative position relctiveto each other by n clnmpin bolt 9 which is situated ct right angles to te division line 1 and extends through on aperture 10 in the heel port onand into on aperture 11 in the fore portion, seid holt hevingscrew-threaded engegement with the not 122 which is anchored in the foreart. In the construction herein shown the ore port of the lost has onspertnre 13 leading thereto from the bottom side through which the nut12 can he inserted end positioned, said not when in piece havingengegement with e shoulder 19. The not is held in piece ngeinst snidshoulder by a. plug it which is inserted into the aperture 13 after thenut is positioned, and said not is held from tnrnin loy wings or ribs 15which extend lcterel'ytrom the not end are embedded in the wood oi thelost.

The heel port of the lost is cut ewey to provide e recess 18 to receivethe heed 17 of the clamping bolt, seid recess heving e sent 18 againstwhich the heed oi the clemping holt fits. $ince the clnmp holt extends'etright enles to the division line 1', it follows that w an the holt istightened the two parts of the last ere very .ol elem d together. Theshoulder it prevents t e nut from giving and the clamping bolt operatesto clamp the two parts of the lost so firmly together that the last willbe sufiiciently rigid for use in the lasting and other similsroperetionsof the shoe.

Iii-order to remove the last from the shoe, the clamping bolt 9 is firstremoved, and then the operatorslides the heel part of the last upwardlyalong the division line 1, as shown in dotted lines Fig. 2, thisoperation shortening the last because of the inclination of the divisionline. After the heel part has been moved into the dotted line position,then it can be swung upwardly into the full line position Fig. 2 toclear it from the top of the counter and the last may then be withdrawnfrom the shoe.

I will preferably provide a connecting member which permanently connectsthe two parts of the last, but yet which allows this sliding andswinging operation. The adventage of such it connecting member is thatall Y danger of the parts of the last becoming separated and one or theother part becoming lost is evoided. The connecting device herein shownis in the form oitwo links 20 which are received in recesses 21 and 22in the fore and heel parts of the last, respectively. Said links arerovided with slots 23, 24', preferably curve as shown, through whichextend pins 25 and 28 carried by the two ports of the lest, thispin-end-slot con nection allowing both the sliding and swinging movementof the heel port of the lest shove reierred to. These links prevent theheel part from being separated from the fore part and thusinsure thatthe two parts of the last will always be together whenever they are tobe used.

Having fully described my invention, what it claim as new end desire tosecure by Letters Patent is:

A last divided diagonally across the instep portion thereof to present aheel part and a fore part, one of the meeting feces of said arts havinge guiding groove extending om one end to the other thereof, and theother having e guiding rib fitting said cove, means to clamp said twoparts rigidly together, said two parts having alined recesw in theirmeeting faces, connecting members loosely occupying said recesses, eschconnecting member having a slot at each end, and pins extendingtransversely through said parts and the recesses therein and through theslots in-ssid connecting members, said connecting members beingpivotally mounted on the slots and permitting both 9; sliding and apivotal movement between the parts of the last while at the same timepermanently connecting them together.

In testimony whereof, I have signed my name to this specification,in'the presence of two subscribing witnesses.
